Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
If you would like to evaluate 2 * a - b for a = 2 and b = 3, you can do this using the following steps:
2 * a - b = 2 * 2 - 3 = 4 - 3 = 1
The correct result would be 1.
Answer:
The smallest positive number that is a multiple of two or more numbers. The Least Common Multiple of 3 and 5 is 15 The multiples of 4 are: 4,8,12,16,20,24,28,32,36,40,44,Say we have listed the first few multiples of 4 and 5: the common multiples are List the multiples of the numbers until we get our first match.
When reflecting over y = -x
The x and y values change places and the signs change.
(-2,5) becomes (-5,2)
